And as unqualified as infants are to observe the Supper (in which every reasonable person will agree with us), even so unfit are they also to receive Christian baptism. And, as infant baptism, for want of testimony from the divine Scriptures, is demonstrated only by arguments and uncertain conclusions, so also, by such and similar conclusions, the Supper may be appropriated to infants, as was formerly done in the Roman church. And as we may by no means, on such human conclusion, admit infants to the Supper, just as little may we on these conclusions admit them to baptism; but in all this all of us who do not wish to be seduced and deceived must necessarily adhere to the doctrine of Christ and his apostles. But, as the Jews adhered unchangingly to the circumcision on the eighth day, without following in any wise their own opinion, even so should all Christians still much more adhere unalterably to the doctrine of Christ, and administer baptism only upon faith and repentance, as Christ has ordained.
But all Christians are commanded and in duty bound to walk before their children with a good example, and to bring them up in the fear of the Lord, by good teachings and instructions, without using on them baptism, the Supper, or any other ceremonies; since it is known that it is impossible for any one to unite another to the Lord, without his will and knowledge.
But as soon as men grow up and arrive at the years of discretion, it is found, that through their innate sinful nature they live after the flesh, and thereby fall from grace, to which they had been bought by the blood of Christ. Their souls then need the hearing of the word of God, whence proceed faith and regeneration, and, as a consequence thereof, Christian baptism; which by Christ has been appended to faith and regeneration, and may never be separated therefrom; and which is represented as a grave in which men are to bury their own actual sins which they have put off, and are thus to rise with Christ to newness of life, and walk after the Spirit.
And as no bath to wash off the filth of the body can be used on an unborn child, but the child must first be born; so Christian baptism, which is compared to the washing of new born infants, can, according to the will of God, be given to none but those who are regenerated by faith, dead to sin, desire the same, rise from the death of sin, and walk in newness of life, observing whatsoever Christ has commanded them.
Hence no one can be recognized as a brother or sister in the church of Christ, with whom any Christian ordinance may be practiced, unless they have previously, according to the word of God, received upon faith the Christian baptism here spoken of, which is the first ordinance and the reception into the Christian communion, by which we submit and obligate ourselves to actually observe all the commandments and ordinances of God. And as there is but one faith and one God, so there is only one Christian baptism, which, having been once received upon true faith, according to the institution of Christ, may not be repeated or renewed.
Of the baptism of John, and how he as a messenger and forerunner sent before Christ, preached the baptism of repentance, and pointed to Christ, read: “John did baptize in the wilderness, and preach the baptism of repentance for the remission of sins.” Mark 1:4; Matt. 3:6,11.
“I indeed baptize you with water; but one mightier than I cometh, the latchet of whose shoes I am not worthy to unloose: he shall baptize you with the Holy Ghost and with fire.” Luke 3:16; John 1:31.
How Christ Jesus commands his disciples to preach the Gospel, and to baptize only hearers and believers of it, and not unintelligent, ignorant children, read: “All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: teaching them to observe all things whatsoever I have commanded you: and lo, I am with you alway, even unto the end of the world.” Matt. 28:18–20.
“He that believeth and is baptized shall be saved; but he that believeth not shall be damned.” Mark 16:16.
How the apostles, pursuant to this high injunction, preached the Gospel, and baptized only the hearers, believers, and self-desiring recipients, read: “When they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do? Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins.” “Then they that gladly received his word were baptized.” Acts 2:37,38,41.
